Description
FastPubSub helps real-time apps deliver messages faster and more consistently across regions. Instead of relying on default Internet routing, it continuously measures path quality between relays and routes traffic around congestion and suboptimal paths. The result is a lightweight global pub/sub layer for live events, fan-out delivery, multiplayer games, and other latency-sensitive workloads. You can also try a few simple live demos to see FastPubSub in action: https://demo.fastpubsub.com/

Could you build this?
No Building an overlay mesh network with dynamic route optimization, latency-probing relays, and high-throughput global pub/sub routing requires deep telecommunications and distributed systems expertise.
What it would actually take: The architecture entails an anycast-routed global overlay network of PoPs running custom low-level proxy relays (written in Rust, Go, or C++) measuring real-time latency, jitter, and BGP anomalies across alternative paths. Relays run proprietary shortest-path routing algorithms and peer-to-peer gossip protocols to bypass suboptimal public internet routes with end-to-end payload encryption. Developing this requires specialized network engineering, low-level socket programming, and global infrastructure orchestration.
